environment) deployed in Tomcat5.0 server. Tomcat server is crashing
frequently when we  access the service. The Web service basically interacts
with Oracle db for data proceesing.


             We are using IBM's JVM (IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9
2.3 Linux amd64-64 j9vmxa6423-20081129 (JIT enabled) ) and the OS is Linux.
Need help on this, here with I am providing the log details.
